Gene Pool, All of the different alleles present in an interbreeding population, Allele, Different variations of the same gene, Fitness, Measure of how well an organism can survive and reproduce in its habitat, Selection Pressure, Anything in the environment that favours one phenotype over another eg. predators, hot climate, disease, Natural Selection, Increased frequency of alleles in a population that code for traits that increase survival, Directional Selection, Natural selection that favours one extreme phenotype, Disruptive Selection, Natural selection that favours two opposite extreme phenotypes, Stabilizing Selection, Natural selection that favours the average middle phenotype, Gene Flow, Movement of organisms between gene pools aka. migration, Immigration, Movement of organisms into a gene pool bring new alleles with them, Emigration, Migration of organisms out of a gene pool take alleles with them, Genetic Drift, Random chance events that remove alleles from a gene pool, Fixed Allele, An allele that has become 100% of the genetic variation in a gene pool, Lost Allele, Allele that has been completely removed from a gene pool, Founders Event, When a small subsample of a larger gene pool starts a new smaller gene pool with less genetic diversity, Bottleneck Effect, When a large gene pool almost goes completely extinct and loses alleles in the process, Sexual Selection, Non random mating due to preference for "sexy" traits that increase likelihood of mating and reproducing, Genetic Variation, The variety of different alleles present in a gene pool, Mutation, Permanent change to the base pair sequence of a gene that can make completely new alleles.
